Collections : [University of Michigan Bentley Historical Library]

Librarian at the Library of Congress, University of Michigan and Northwestern University, and bibliophile. Correspondence, articles and pamphlets, papers relating to his books and articles, and topical files relating to his interest in Carnegie Libraries, literary forgeries, the work of the American Library Association's Library War Service during World War I, library Americanization programs, 1919-1921, and the library building of University of Michigan; also photographs.

The Koch papers are very incomplete for the part of his career before he went to Northwestern. Much of the earliest correspondence deals with the gathering of material for his "A Portfolio of Carnegie Libraries," Very little material on his work at the University of Michigan has survived, although a few reports from Byron A. Finney on the operation of the library and copies of Koch's proposal for a new library in 1915 are included in the collection.

Although the collection is much larger for the years after 1919, it is apparent that even for these years many of his professional files were either retained by the Northwestern University Library or destroyed. There is surprisingly little information on the activities of the A.L.A. or other professional organizations. Much of the correspondence consists of family and personal mail rather than the activities of the Northwestern library.

A high proportion of the material from this period relates to the writing and publication of his many books and pamphlets. Although Koch's files on Carnegie libraries, literary forgeries, the A.L.A. Library War Service, and Americanization programs may be of interest to scholars, many of his publications involved the translation and publication of works aimed merely at bibliophiles. These works were often published by such groups as the Caxton Club of Chicago or the Roxburgh Club of San Francisco which are interested in printing as an art form.

Mathematician, professor of mathematics at the University of Michigan. Correspondence and other papers relating to professional and family matters, to his association with the Bethlehem Church in Ann Arbor, and to his involvement with the American Mathematical Society, especially regarding the controversy over loyalty oaths in the 1950s; also letters from family members, notably sister Martha, a school teacher, who comments on her career and her life as a single woman; and letters from son Paul during World War II; and photographs.

The papers of T.H. Hildebrandt consist of seven linear feet of materials spanning the years 1887 to 1978. The bulk of the collection falls between the years 1930 and 1960. The papers have been arranged in ten series: Biographical Material, Bethlehem Church, Compositions, Correspondence, Lectures, Notes, Organizations, Universities, Writings, and Visual Materials.

As Hildebrandt was fairly well known in his field, he corresponded with other eminent mathematicians of his time, including Eliakim Hostings Moore (with whom he had studied) and Maurice Frechet. The Hildebrandt papers are also valuable for other topics: the development of mathematical ideas and the various pressures placed on academics during the Cold War to name both two examples.

Pillsbury was professor of psychology at the University of Michigan from 1897 to 1942. His papers include family and professional correspondence, University of Michigan materials, writings, and photographs.

The Walter B. Pillsbury papers consisting of correspondence, course materials, writings, and photographs documents the career of one of the significant leaders in the early development of psychology as a discipline. The collection was received in three principal accessions from Pillsbury and members of his family. The series in the collection are Biographical/personal, Professional Files, Photographs, and Family Papers.

The collection also includes manuscripts of published and unpublished books and articles, biographical material, scrapbooks and notebooks detailing the University of Michigan expeditions to the Pacific and Greenland, and travel notes of trips to the Near East, Spain, the West Indies, Switzerland, and Russia.
